Description
The Rotor Q Ring Q39t is an oval chainring designed to smooth out dead spots in your pedal stroke, making it a compelling upgrade for riders who want more efficient power transfer on long climbs, training rides, or race day. Fitted as an inner chainring with a 110x4 BCD, it suits a wide range of road and gravel double-chainset builds. Cobbled Climbs is the authorised retailer for Shimano in India.
Use Cases
Daily training. Reliable use across Indian training conditions — heat, humidity, and rough tarmac.
Race day. Performance-grade construction for competitive efforts.
Long rides. Built for full-day rides across Western Ghats, Sahyadri, or Nilgiri climbs.
Our Take
On the long climbs out of Lonavala or the grinding ascents toward Ooty, cadence consistency matters more than raw power. Rotor's oval Q Ring geometry reduces muscular fatigue by loading the legs through their strongest arc and easing pressure through the dead zone. At Rs. 3,800, this is a worthwhile upgrade for riders who log serious kilometres in India's heat and hilly terrain and want to get more from each pedal revolution.
Sizing for Indian Riders
This is a 39-tooth inner chainring with a 110 BCD, 4-bolt pattern — confirm your crankset matches before ordering. There is no European-to-Indian size conversion needed, but do verify your chainline suits the inner position. Riders running compact or semi-compact double setups on Pune or Delhi sportive builds should double-check outer ring pairing for clean shifting across the full range.
Compatibility Notes
Fits 110 BCD, 4-bolt cranks — common on many Shimano, SRAM, and third-party road cranksets. Confirm 10, 11, or 12-speed chain compatibility with your groupset. Clean the chainring regularly; India's monsoon grit and dust accelerate wear noticeably. Inspect for chain skip every few thousand kilometres and replace the chain before it damages the ring's oval tooth profile.
Pairs Well With
Complete the drivetrain upgrade with a quality chain suited to your groupset speed, a wet-condition chain lubricant for monsoon riding, a chain wear checker to protect your investment, and a matching outer Q Ring chainring if you want the full oval pairing across both rings.

Frequently Asked Questions
What is the Rotor Q Ring Q39t best used for?
The Rotor Q Ring Q39t is best suited for road cyclists who want to improve pedalling efficiency on long climbs and extended training rides. Its oval profile reduces fatigue through the dead spot of each pedal stroke, making it particularly useful on sustained ascents like those found in the Western Ghats, Coorg, or the climbs around Shimla.
What size Rotor Q Ring should I order for my crankset?
This specific ring is a 39-tooth inner chainring for 110 BCD, 4-bolt cranksets. Before ordering, confirm your crankset's bolt circle diameter and bolt count. The 110x4 BCD is common on many Shimano and SRAM road cranks, but always verify — an incorrect BCD means the ring will not mount. Tooth count should also match your intended gearing range.
Will the Rotor Q Ring hold up in monsoon conditions and Indian heat?
Yes, with proper maintenance. India's monsoon season and 35°C+ heat accelerate chainring wear if the drivetrain is neglected. Clean the ring after wet rides, use a wet-condition lubricant through the rains, and inspect the tooth profile regularly. Switching to a dry or wax lube post-monsoon will help extend the life of both the ring and your chain.
How does the Rotor Q Ring compare to a standard round chainring?
A standard round chainring applies consistent resistance throughout each pedal revolution, including the mechanically weaker dead zones at the top and bottom of the stroke. The Rotor Q Ring's oval shape reduces effective resistance through those dead zones and increases it through the power phase, aiming to smooth out pedalling force and reduce leg fatigue over long distances.
Is the Rotor Q Ring worth Rs. 3,800 in India, and what warranty does it include?
At Rs. 3,800 with free delivery above Rs. 2,500 and cash on delivery available across India, the Q Ring represents solid value for a performance-oriented chainring upgrade. Rotor products are covered by the brand's standard manufacturing warranty against defects. For warranty claims or support, contact Cobbled Climbs directly — our team can assist with the process from Mumbai.
